Google Analytics 4 - simple example of service account API usage in Java?

Question

I've spent a few days trying to get an example of how to do the above - use a service account to non-interactively get Google Analytics metrics using the GA4 API from Java.

The official example at

https://developers.google.com/analytics/devguides/reporting/core/v4/quickstart/service-java#3_setup_the_sample

has a requirement that you need to provide a "view ID" when initializing the GA4 client classes.

Nowhere can I find a "view ID" -anywhere- in my GA4 profile. I do have the JSON file with my credentials, have connected the GA4 property, created a service account, etc.

View IDs seems to be something used previously with Universal Analytics, which was discontinued 1 July 2023.

Additionally, what is the difference between "Reporting" and "Data" APIs in Google Analytics?

I've also found an official Google example of the "Data" API at

https://developers.google.com/analytics/devguides/reporting/data/v1/quickstart-client-libraries

but there is a step that refers to setting an environment variable to define where to find the authentication JSON file - but where / how is an environment variable set in a headless JAR that will run on a different machine than where the JAR is being compiled (headless Linux server)?

How can I set the credentials JSON file location in the code (NOT an environment variable) per the data API example?

Trying to accomplish this in a Java Spring Maven App in NetBeans.

Thanks

Answer 1

The answer to my question's core issue, e.g.

How can I set the credentials JSON file location in the code (NOT an environment variable) per the data API example?

Was this code:

GoogleCredentials gc = ServiceAccountCredentials.fromStream(this.getClass().getResourceAsStream("/client_secrets.json"))
                    .createScoped(Collections.singletonList(StorageScopes.DEVSTORAGE_FULL_CONTROL));

            BetaAnalyticsDataSettings betaAnalyticsDataSettings = BetaAnalyticsDataSettings.newBuilder().setCredentialsProvider(FixedCredentialsProvider.create(gc)).build();

            BetaAnalyticsDataClient betaAnalyticsDataClient = BetaAnalyticsDataClient.create(betaAnalyticsDataSettings);

with my client_secrets.json file located in my NetBeans Maven project tree at the location

Projectname
 |
  src
   |
   resources
    |
    client_secrets.json

and my imports for the above is:

import com.google.analytics.data.v1beta.BetaAnalyticsDataClient;
import com.google.analytics.data.v1beta.BetaAnalyticsDataSettings;
import com.google.analytics.data.v1beta.DateRange;
import com.google.analytics.data.v1beta.Dimension;
import com.google.analytics.data.v1beta.Metric;
import com.google.analytics.data.v1beta.RunReportRequest;
import com.google.analytics.data.v1beta.RunReportResponse;
import com.google.api.gax.core.FixedCredentialsProvider;
import com.google.api.services.storage.StorageScopes;
import com.google.auth.oauth2.GoogleCredentials;
import com.google.auth.oauth2.ServiceAccountCredentials;

E. g. using the above I was able to reference my GA4 API credentials client_secrets.json file by direct reference in the code and not via an implied environment variable.

Answer 2

Try this.

GoogleCredential gc = GoogleCredential.FromStream(Utility.GetStreamFromResourceFile("C:\\Development\\FreeLance\\GoogleSamples\\Credentials\\credentials.json", GetType()));
BetaAnalyticsDataSettings betaAnalyticsDataSettings =       BetaAnalyticsDataSettings.newBuilder().setCredentialsProvider(FixedCredentialsProvider.create(gc)).build();
BetaAnalyticsDataClient betaAnalyticsDataClient =      BetaAnalyticsDataClient.create(betaAnalyticsDataSettings);
